## MIT Compliance

This implementation uses **only** Proxmox VE/PBS API documentation as specification. No PDM source code was used or referenced during implementation.

**Key Principles:**
- Clean-room implementation from scratch
- Use official Proxmox VE API docs (port 8006)
- Use official Proxmox PBS API docs (port 8007)
- No code copying or reference to PDM source

## Next Steps

1. **Create remaining UI components**:
   - VM manager interface
   - Backup manager interface
   - Ceph manager interface
   - SDN manager interface
   - Firewall manager interface
   - HA groups manager interface

2. **Update documentation**:
   - Create `docs/wiki/Proxmox-Management.md`
   - Update `docs/wiki/Home.md`
   - Update `docs/wiki/Architecture.md`
   - Update `docs/wiki/IPC-Commands.md`

3. **Release v1.2.0 pre-release**:
   - Create GitHub release with pre-release checkbox
   - Update CHANGELOG.md
   - Update release notes
